The 5mm RGB Diffused LED (4-Pin) is a compact, multicolor light-emitting diode that combines three primary colors—red, green, and blue—into a single LED package. By controlling the brightness of each color independently, it can produce a wide range of colors for electronic projects, visual indicators, and decorative lighting.
Its diffused lens distributes light more evenly, creating a soft, blended glow. The standard 5mm through-hole design makes it easy to install on breadboards and printed circuit boards (PCBs), making it suitable for Arduino projects, robotics, electronic prototyping, and educational applications.
The four-pin configuration provides separate connections for the red, green, and blue channels, along with a shared common terminal. Use suitable current-limiting resistors to protect the LED during operation.
